To all" whom it mayfconcern: I

Be it known that I, me ltimes, a citizen of the United States;residingat Cincinnati, inthe county of H'zit'nilton and State of Ohio,have invented certain new and uselful Improvements in Filli'n Machinesof which the following is a specification.

My intention relat'estothat cl'ass'of'lilling rm-iehine where containersare filled automatically to a certain height, and where hottles arelilted and loiiei'etl 'to the lilling' mechanism proper. 'My mechanismthus belongs particularly to that cla'ss of niac'hinery which fills twokinds of lihui'dssueh as syrups first and then carbonated wateratterwards; and to that class ofmaehinery where filling is done under apressureditl'erent from the atmosphere. I

It eon-Sims also of novel filling inechanisni and other parts, such asdescribed 'tt'inf'ther in detail.

"In the drawings: Fig. 1 is an upright viewof part ol th'eniechanisinfand a ertical cross section of other parts of the mechanismin the same figure; I 4

Fig. 2 shows a detail ot'the star feed. The filling machine consists ofthe main base A which carries t1ie'inte1-iormain bearingfor the table Band fillingniechanis'm C. The tank isadjastable as totlie distan e fromthetable as'in the manner of the filling machine shown in Fig. 3 of my-Patent No. LO'lLllS of Feb. 13th, 1912, and I neednot, therefore;describe these details disclosed by a prior patent I I The bottle liftin my present invention has the desirable :Eeature'that when the bottleis pressed against the filling tube D, whereby spiral springs 2 haveto'be conipressed so as to effect an airtight seal on the bottle,thenthe littingeapacity of this bottlc lifting mechanism is multipliedin proportion to the increased power that is re quired to coinpress saidsprings. A mechanism producing similar results I have had patented to mein anon-rotary fillingrni'achine, Patent-No. 1,115,834 'ofNo v. 13,1914,that consists of a combination of hits. The same desirable results Ireceive in rotary filling machines by a crank F mechanismhavingpreferably three arms.

In Fig.1, E is a bearing for this triple crank F. The bottle rackscons'st of the forks G in which bottle t'able 3 is carried by means oi?the shaft -l-. These Forks have a lowersurlace 1'1aae'h-1-y11a0ks 5 thatswing in these forks t ne-1.11 01" round pins '6. Only alewot'thesebottle racks and lifts are shown so as not to obscure the drawing.

The shaft parts 1 move in openings in the table B. ill these openingsare tubular projections :8, some of th'e'n'r shown in Figs. 1 and 2;which serve another purpose to be described later.

k i The "fork is guided against the spider cast 'ing H byinea ns ofrollers 9', which allow the bottle l orksG to l reel-yfiiiove up anddown. Fasten ed up'oa the s me 'colinnn that carries the table B and thespider 'H is a large bevel gear K into which engages a small bevelpita-0 10 that 'is' fastened upon the same shaft 'asthe crank' Fahdtherefore etlecti the niolveiiient of'this crank.

f The table of the machine is shown in the drawi'ng toniove froin rightto lelkthatis, ii'liile looking dowiiiipon the whole ine'cha-'iiisn'n'in the direction of a clock. It plain- 1y e'Videntfrom thedrawil'igs'ho'w the bottle racks Gare raised by means of this crank.Rollers 12 are located on the "ends of this triple crankto reduee'thefriction; It is necessary to time the s'rnallbevel pinion 1O andithela'rge'bevel gear K sothat one oi? the crank arms of the triple crank Fcorres-ponds 'infits motion to one bottle rack G.

For instance,it Iliave a machine with A bottle racks, the cr'ank F hasto make eight revolutions. More or less tllanthree arms ni'ight tensedin this crank mechanism but I obta'in good results from thistriplecrank. It is evident that wh'enthe bottle rack is ap roximatel at itshighest position the upper crankarin eXerts a greater force upon thesebottlelitts and easily coinpresscs the springs. It is also er ident thatat the lowest position these crank arms start their work lifting thesebottle racks much easier and start the lifting of the bottle without anyjar, increase their speed and presses the bottle with increased force'against these springs. hen the bottle rack is at its greatest. heightand the bottle 'is pressed against the seal, these bottle racks G arelocked by means of the hooks 5 which en- 'gageithe spider casting asshown at the extrein'e left of the drawing. These books have twosurfaces at an obtuse angle the upper surface 13 being the edge of amiddle rer- \tica-l rib, a nd the lower. surface 11 being flat. Theuppersur'tacc 13 is engaged by a spring 15 which hit the hook intoposition Ti l shown at the extreme left. The lower ring of the bottlerack does not require any different mechanism than is shown in patent tome No. 1,017,418 of Fig. 1; it will roll down an inclined way L. Thesehooks 5 are thrown out immediately before sliding down the inclined wayby another spring 16 which engages the surface 14 of the hooks 5.

The driving of the machine is effected by another bevel pinion 17 drivenby a pair of spur gears, shaft 18, endless chain 19, worm 20, and motordrive 21.

I will now describe the mechanism which is used in conjunction with thisfilling mechanism to measure a certain quantity of syrup into thebottles before they are filled with the second liquid, which in thiscase we assume to be carbonated water. The proportion of syrup in thecorbonated product is usually one in seven, that is, one ounce of syrupis usually first filled into the bottle and then six ounces of water aredeposited later.

In most machines where bottles are fed automatically there is usually aso-called star feed which takes the bottles from the convcyor andtransfers them to the filling machine proper. This star feed is shown inFig. 1 by S, also in Fig. 2. A conveyor 22 is shown in cross section inFig. 1 and in partial plan view inFig. 2, which brings the bottles tothe star feed. While transferring from the conveyor to the fillingmachine table 3, the bottle describes a semicircular pathway followingthe star feed,

and during this part of the motion syrup is first put into the bottle bymeans of a device which in a certain form is patented to me in my PatentNo. 1,313,301. This filling device consists of a rotary pump P in my)resent applicatiom'and 28 of Fig. 1 in my atent No. 1,313,301. In mypresent application this device is driven by bevel gear system 23through shaft 18, and then by bevel gears 23 and spur gears 24 and 25.One or more of these gears 24 and 25 are interchangeable so as to varythe capacity of the pump. There is also an interchangeable head andvalve plate in this present appli cation, 26 and 27, and 10 and 17 ofthe patent mentioned above, No. 1,313,301, and the hose connection forthe pump to this interchangeable head.

Asthese parts are sufficiently described in my previous patent, it isnot necessary to elaborate on same in this application. I will simplysay that the bottles in the star feed S describe a pathway ofapproximately 180 degrees, which is more than sufficient to supply thesebottles with the required amount of syrup. While there are only fourspouts provided in this present application as against seven spoutsshown in my Patent No. 1,313,301 referred to above, this does not makeany difference in operation, as any number of spouts could be used if sodesired.

Having described my invention what I claim and desire to secure byLetters Patent is:

1. In a filling machine, a rotary filling means, a container-feedingconveyor, rotary container-delivering means delivering containersdirectly from said conveyor to said filling means, a second fillingmeans comprising a circular series of spouts rotating continuously withsaid delivering means, a supply conduit intermittently connected withsuccessive ones of said spouts, and forcing means delivering substancecontinuously to said conduit to be discharged by said spouts intorespective containers while the containers are being delivered by saiddelivering means.

2. In a filling machine, filling means, a carrier, a lifter movable toand from said filling means and carried by said carrier, a crank movablein the path of said lifter, to engage and lift said lifter toward saidfilling means as said lifter passes said crank, and. means for drivingsaid carrier and said crank in unison.

3. In a filling machine, filling means, a carrier, lifters movable toand from said filling means and carried by said carrier, a crank havinga plurality of arms and movable in the path of said lifters to causesuccessive ones of said arms to engage and lift successive ones of saidlifters toward said filling means as said lifters pass said crank, andmeans for driving said carrier and said crank in unison.

4. In a filling machine, movable filling means having a plurality offilling spouts, a carrier, lifters movable to and from respective onesof said spouts and carried by said carrier, a crank movable in the pathof said lifters to engage and lift successive ones of said lifterstoward said filling spouts as the respective lifters pass said crank,and means for driving said carrier, said filling means and said crank inunison.

5. In a filling machine, rotary filling means, a crank, a lifter raisedby said crank to lift containers toward said filling means, supportingmeans to hold said lifter up after said lifter is raised by said crank,but leaving said crank free to descend therefrom as soon as said lifteris lifted, means to release said supporting means after it has beenraised for an interval, and means for driving said filling means andsaid crank in unison.

In testimony whereof I have signed my name in the presence of twosubscribing witnesses.
